I have seen some assets for my game… 2 has a license file in which you can use it anywhere but one is from epic games store which is free. So Will I still be disqualified if I use that. Here is the link : https://www.unrealengine.com/marketplace/en-US/product/animation-starter-pack?sessionInvalidated=true

I can't really find much about the license, it just says only use in Unreal Engine, so you should be fine :)

Thanks
